Jackson Chourio went 3 for 3 and drove in three runs in the first two innings before departing with a hamstring injury as the Milwaukee Brewers trounced the Chicago Cubs 9-3 in their NL Division Series opener. Chourio became the first player to have three hits in the first two innings of a playoff game. But his availability for Monday’s Game 2 in the best-of-five series is unclear. Chourio, who missed a month of the regular season with a strained right hamstring, left with tightness in that hamstring after beating out a bases-loaded infield single.
